Wow! Futurlec's pinout boards are super cheap! But unfortunately, as you say, they're not DIL. I might order some anyway. I want to tinker with some SMT chips.ericwertz said:It's not DIL, but it's 0.1". $0.90.

Otherwise, you might be able to design some yourself through someplace like BatchPCB, but you're probably looking at 4 for $40-45 or so.

Hi 3v0. I'm equipped to do photofab boards. I've been meaning to get doing it again for a while anyway. I print the artwork with my laser printer. Makes beautiful, precise boards.If you have a laminator and a laser printer you can buy a pack of paper and green foil from Pulsar for about $25 (+etchant)
and make as many as you need.
Ya, I should have no problem with it. Just have to stop being lazy and do it.Anyone who can figure out how to solder a 64 pin QFP can make
a small board. With less then 100 holes it is possible to drill
them with a pin vise. As you move more parts to the etched board
the number of external pins drop.
I've run into that a few times, and learned, as you say, to always plug something into those before soldering to keep them aligned.Not too sure but I think the inexpensive header pins from futurlec use
a somewhat low melting point plastic and are more apt to become
unaligned during soldering.
3v0,
Don't wish to hijack this thread with a tangent, but 0.5mm pitch IC's are tough for the toner transfer method...its not the width of tracks (I've managed 8mils with any paper) its the gap between SMD pads...which can be 0.1-0.15mm.... With so little room for error, it doesn't lend itself well to toner transfer, although I'm sure it can be done.
For photoetching however, its all down to the artwork
Futz, if you're feeling lazy I could attempt to design an adapter for you in eagle? I've done so many little boards/adapters it's not really a hassle..just something else to add to my library. Just say the width spacing you want (0.3" isn't really on the cards, more likely 0.6" like a DIP40).
That's Schmartboard.Bill talked about a place that makes adaptor boards, could be smartz boards or similar. They use a process that raises the level of the PCB surface such that the leads sit in wells. Makes soldering a breeze. Or so they say. If I find the URL...
Try Proto-Advantage, they're much more reasonably priced:
They have an LQFP-64 to DIL/DIP adapter for $14.99.
